Starting to worry now. In fact she doesn't really respond to anything unless it involves singing and silly faces, then she will laugh at me. I don't think she understands anything. I believe her hearing is fine because she looks up when there are noises outside or elsewhere in the house. She is great with the physical stuff and constantly on the go, everything fascinates her. Got a phone appt with the HV next week. Has anyone else been in the same boat? My gut is telling me ASD or ADHD
